Hello, having a problem where the meshes which i'm importing to my URDF file are absolutely huge. The dimensions are correct in solidworks (around 400mm cube). I tried changing the units of the part back to meters as i was working in mm and this had no effect. Any idea what i'm doing wrong?
It seems that there isn't a way to specify units in STL files. So whatever unit you use will be treated as meters by Gazebo. That's why your 400 mm cube came out as a 400 m cube.
Your solution seems to be the easiest one, to specify a scaling factor for the mesh on SDF, from mm to m for example:
<mesh>
<uri>model://model_name/meshes/your_mesh.stl</uri>
<scale>0.001 0.001 0.001</scale>
</mesh>
An alternative would be to rescale the mesh with an external editor.
That worked for me. just remember to write it down under every <mesh> part of the world code. Thank you!

It would help if you're able to share your STL and URDF files. You can just update the question.
I dont really know what was causing this, maybe the fact that the solidworks model was developed in mm rather than m, i ended up just using a scaling tag and setting the three parameters to 0.001 and it imported fine
